Problems related with the modeling and dynamic response to blast loadings of doubly-curved sandwich panels with laminated face sheets are developed. In this respect, the implications of the panel curvature, of anisotropy and stacking sequence of face sheets, of transverse orthotropy of the core, and of structural damping on dynamic response to timedependent loads are highlighted. As concerns the blast pulses considered in this analysis, these are related to in-air explosions or of traveling shock-waves. Other parameters, mainly geometrical, are also considered in the numerical simulations, and their implications on the dynamic response are put into evidence. Due to the absence of similar results in the specialized literature, this paper is likely to fill a gap in the state of the art of this problem, and provide pertinent results that are instrumental in the design of advanced sandwich shells operating in a dynamic environment. Moreover, the closed-form solutions developed in the paper, can serve as excellent references for comparison with numerical based solutions.

The problem of the dynamic response of flat rectangular sandwich panels subjected to underwater and in-air explosions is analyzed. The study is carried out in the framework of a geometrically non-linear model of sandwich structures featuring anisotropic laminated face sheets and an orthotropic core, in conjunction with the unsteady pressure generated by an explosion. Effects of the core and of the orthotropy of its material, as well as those related to the ply-thickness, directional material property and stacking sequence of face sheets, geometrical non-linearities and of the structural damping ratio are investigated, and their implications upon the dynamic response are highlighted. To the best of the authors knowledge, the specialized literature addressing the dynamic response of sandwich structures to underwater and in-air explosions is rather scanty. This work is likely to fill a gap in the specialized literature on this topic
